3-Stage Gear Motor (2 UDL 1.5kW and 1 WPDS 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100) is a gear motor line assembled from an electric motor, specifically a 3-phase electric motor combined with a gearbox, specifically a 3-stage gearbox. With a right-angle output shaft design and compact dimensions, the motor is easily installed in systems with limited space or requiring flexible transmission redirection. This motor assembly provides extremely low speed, stable traction, and smooth movement, meeting the requirements of various industrial machinery operating continuously.

General Design of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100) is optimized for durability, load-bearing capacity, and transmission efficiency. Three reduction stages are arranged in series according to the mechanism of speed variation → intermediate reduction → main reduction to ensure smooth output speed reduction, high torque, and no shock load phenomenon. The housing of the motor and gearbox is made of solid cast iron or aluminum alloy.

Detailed Structure of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100)

The 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100) is a gear motor line from 1.1kW to 3.7kW assembled from a 3-phase 1.5kW 2Hp electric motor with a 3-stage gearbox (2 UDL 1.5kW and 1 WPDS 100) featuring the detailed structure as follows:

Electric Motor Structure:

• Outer housing: Cast from heavy-duty cast iron or aluminum alloy, acting to protect internal components and dissipate heat through vertical ribs.
• Rotor: Precisely CNC-machined rotating shaft, ensuring concentricity to seamlessly transmit traction force to the gearbox without warping.
• Stator: Magnetic core containing pure copper windings, capable of withstanding high operating temperatures when the machine runs continuously under heavy loads.
• Terminal box: Tight-sealed wire outlet design, achieving IP55 protection level, ensuring electrical safety at power cable connection points.

Gearbox Structure:

• 1st and 2nd stepless speed variation stages (UDL assembly): Two mechanical variators connected in series, allowing speed adjustment via a conical disc friction knob without using electronic frequency inverter devices.
• Final reduction stage (WPDS 100):Worm gearbox series with the input connection shaft located on top. The alloy steel worm shaft drives a wide-face bronze worm gear, generating extremely high twisting torque.
• Auxiliary transmission system: Shaft journals are supported by industrial heavy-duty bearings and immersed in specialized grease/lubricant, reducing gear friction.

Common Applications of the 3-Stage Gear Motor (2 UDL 1.5kW And 1 WPDS 100)

With the advantages of generating ultra-slow speeds, powerful traction from the 1.5kW motor, and a design elevating the power generation assembly, this equipment is mainly applied in:

• Chemical mixer systems, industrial wastewater treatment tanks where liquid splashing onto the electric motor must be avoided.
• Cargo lifting winches, gantry cranes, or heavy-duty mechanical assembly lines requiring high braking capacity.
• Heavy-duty conveyors, inclined material bucket elevators in cement manufacturing and ore mining plants.
• Various crushers, rubber extruders, recycled plastic molding machines requiring high torque and stable slow rotation to crush materials.

Guide on How to Install the Electric Motor with 2 UDL and 1 WPDS

To install the electric motor with 2 UDL and 1 WPDS, the steps must be performed in the correct order to ensure tightly connected components, stable transmission, and the desired deceleration efficiency.

Step 1: Install the electric motor to the first UDL

Insert the shaft end of the electric motor into the input shaft of the first UDL variator. Check the concentricity between the components, then evenly tighten the bolts to create a solid connection, helping to limit vibration and increase operational stability.

Step 2: Connect the second UDL

Connect the output of the first UDL to the input of the second UDL. Align the assembly position for smooth shaft rotation, then secure all connection points. Two consecutive UDL units will expand the speed adjustment capability before transmitting force to the gearbox.

Step 3: Complete with the WPDS gearbox

Install the motor assembly and two UDL units onto the WPDS gearbox, while checking the fit between the key, shaft, and flange. After tightening the bolts, manually rotate the shaft to ensure the transmission system operates smoothly before putting it into operation.

Combining two UDL variators with the WPDS gearbox forms a 3-stage transmission system capable of flexible deceleration, maintaining high torque, and well meeting low-speed requirement equipment such as mixers, conveyors, presses, blenders, and many industrial transmission systems.
